Abstract (en)
[origin: WO9400628A1] In a continuous heat-treating machine for synthetic fiber tows, this invention provides a method of maintaining a pressure which causes less leakage of a heat medium vapor and provides high stability in maintaining the pressure of a pressure chamber. An aspect ratio of an outlet seal portion of the pressure chamber is set to be smaller than that of an inlet seal portion of the pressure chamber. The method of the invention causes smaller damage to the fiber to be heat-treated, provides a small unit requirement of a heat medium vapor, and is excellent in operation stability and uniformity of heat-treatment.
